![]() ![]() Often searchers add a word that must appear in either the subject / keywords or article title fields, in order to limit to a smaller, more relevant result set.īoth the Tips for searching and the Use Boolean, wildcards and truncation pages have more advice on creating effective search strategies. ![]() Most search interfaces also permit you to add an extra term to restrict your results. Also the Scopus database has a useful Type = Review to restrict to review articles) (e.g., journal article or conference paper. Language (e.g., restrict your results to English language).Year of Publication (range, e.g., latest ten years).Classification Schema (for both Inspec and Compendex databases).Controlled Vocabulary Subject Term (both Inspec and Compendex databases boast a subject thesaurus). ![]() Keyword (author supplied key words and phrases).The facets in the database record typically used to focus a search result set are: To achieve greater precision search statements can be restricted to specific fields, typically: keyword, controlled vocabulary subject, abstract and title fields.Īll the above-mentioned search interfaces feature a left-hand panel that allows you to refine your search result listing, based on fielded data. Use with caution to avoid introducing unwanted results. Note: some database search engines use alternative characters $ ? to truncate. Truncation is an alternative strategy to using the Boolean OR operator. Placing quotation marks around a word string specifies that you are searching for "an exact phrase", a literal string of text, e.g., " strain measurement" OR statements get processed before AND statements. Exactly as in Boolean algebra search statements inside the inner most parentheses get executed first. Synonyms and alternate terminology must be grouped together inside parentheses and linked by the OR operator, e.g., Use parentheses (brackets) to logically group and specify the order in which your search terms should be processed. Truncate a word with an asterisk * wildcard to retrieve variant right-handed grammatical endings, e.g., The nested Boolean search statement above returns a focussed result set limited to where the additional concept "strain measurement" appears as a phrase. Will return a broad result set containing any of those three synonyms. Asterisk An asterisk can be used to search for any variation of a root word truncated by the asterisk. For example, to find people talking about having fun in Disney World or Disneyland, search for ('disney world' OR disneyland) AND fun. ((arch OR bridge OR viaduct) AND "strain measurement") Use parentheses to separate multiple boolean phrases. To narrow your search on a specific aspect or facet use the AND operator to introduce an additional concept, thereby focussing your search result, e.g., To broadenyour search to encompass alternative terminology use the OR operator to group synonymous alternative keywords, e.g., QUT Library Search, Engineering Village, Scopus, Web of Science (WoS) and Google Scholar. Focus that result set with the AND operator.īoolean operators can be used in nearly all search engines and literature discovery databases including (but not limited to):.Broaden the scope of your search with the ORoperator, then.Logical application of Boolean operators allows you to link your search terms, keywords and "key phrases" to first ![]()
